If either the set view limit or the designated time limit for viewing is exceeded, the PDF will be automatically deleted.

In the context of this product's time limit security feature, 'activation' refers to the process of initiating restrictions on viewing by commencing the count of views for a specific PDF and recognizing PDFs that become subject to deletion upon exceeding the specified view limit or time limit.
Activation ensures strict limitations on viewing for the same PDF.
Even if a copy of a PDF with time limit security is made before the specified view limit or time limit is exceeded, the PDF cannot be viewed if it does not match the result of the activation process.
